One of our clients is having a problem uploading to our WS_FTP 5 Server. During an upload, the the Fetch client will suddenly drop the connection. This is happening intermittently and has been difficult to reproduce. We are noticing RPUT_SENDING errors in the Fetch log - but have no idea what they mean. Can someone shed some light on this error? Here is the Fetch log (the asterisks are to mask identity):

From the transcript it looks like it's the server that's dropping the data connection, and sending the message about the transfer being canceled (FTP clients drop the data connection to mark the end of an upload, so if it was Fetch dropping the connection the server would not report an error).

Would it be possible to get a packet trace of the failure, using tcpdump or some similar tool? That would probably clarify what is happening on the wire.
